The apparatus, as applied to a pneumatic dispatch, comprises a series of incoming and outgoing pneumatic tubes 1, 2 respectively, the incoming tubes being delivered into two tubes 1<a>, 1<b> the entrance of carriers arriving along the tube 1 to these two tubes being controlled by an automatic distributing device D so that one kind 'of carrier delivered to the tube 1<a> passes to a conveyer-belt 30 on the cashier's side of a desk A, while the other kind passes through the tube 1<b> on to one of two conveyer belts 50, 51 on the charge-authorizer's side of the desk. The outgoing terminals 2 are preferably arranged at one end of the desk A near the return-clerk's station B. The partition 12 enclosing the belt 30 has openings at intervals provided with swinging gates 32 hinged so as to be swung diagonally across the belt 30 in such a manner that when one or more gates are open, all carriers delivered to the belt on the left-hand side of the gates are swept from the conveyer and roll by gravity down the shoots 40 immediately in front of the cashiers. The carriers delivered to the belts 50, 51 pass to a distributor seated at C who delivers them to charge-authorizers at Y by means of belts 60, 61, and after the cashiers and charge-authorizers have examined the carriers they are thrown through windows 13 provided in the partitions 12 of the desk A on to a conveyer 45 which delivers them to the return-clerk at the station B. The invention is also applicable to mechanical dispatch systems.

Patent GB-836828-A (GB)
Title: Process for the manufacture of glyoxal
IPC: B01J23/89
Filed: 1956-11-26
Abstract: Catalysts used in the oxidation of ethylene glycol vapour to glyoxal comprise silver and/or silver oxide supported on a carrier.  Suitable carriers are, for example, pumice, silica gel and aluminium oxide. Especially suitable catalysts are obtained by applying silver oxide, obtained from silver nitrate by addition of sodium hydroxide solution, to pumice in the presence of a solvent, removing the latter and reducing the silver oxide. Alternatively, a mixture of silver oxide and the silver salt of an organic acid, e.g. silver oxalate, may be applied to the carrier and the mixture heated.  It is advantageous to add promoters, for example copper, copper oxide, copper salts or titanium oxide.  In the examples, the following catalysts are used: (a) silver deposited as pumice; (b) silver oxide deposited on pumice; (c) a mixture of silver oxide and silver oxalate deposited on pumice, the mixture being heated to decompose the oxalate; (d) silver oxide, copper oxide and barium peroxide deposited as pumice and (e) silver oxide and barium peroxide deposited on pumice.ALSO:Glyoxal is prepared by oxidizing ethylene glycol vapour, in the absence of an inhibitor, with a mixture of air and nitrogen in the presence of a catalyst which consists of silver and/or silver oxide and is supported on a carrier.  Suitable carriers are, for example, pumice, silica gel and aluminium oxide.  It is advantageous to use a promoter, for example, copper salts or titanium oxide.  The oxidation is effected generally at a temperature between 300 DEG  and 450 DEG  C.  In the examples ethylene glycol in the vapour phase is oxidized with a mixture of air and nitrogen using as catalyst (a) silver deposited on pumice; (b) silver oxide deposited on pumice; (c) a mixture of silver oxide and silver oxalate deposited on pumice and heated to decompose the oxalate; (d) silver oxide with some copper oxide and barium peroxide deposited on pumice; and (e) silver oxide with some barium peroxide deposited on alumina.

A rotary stepping member 4 carrying contacts 7 is angularly stepped to an intermediate position upon depression of a push-button 1 by the engagement of inclined surfaces on the push button with teeth 41 on the rotor 4, and on release of the push-button the step is completed by engagement of the rotor teeth with inclined surfaces on fixed ribs 5. Button 1 is guided for axial movement and prevented from rotating by interlock ribs 5. Depression of button 1 against spring 8 causes its inclined surfaces to engage the rotor teeth 41 after a dead travel 10; further depression of button 1 urges the rotor 4 against action of a conical spring 9 to disengage contacts 7 from fixed contacts 6, and to free teeth 41 from their normal location between ribs 5 and partially rotates the rotor 4. Release of button 1 now allows spring 9 to urge teeth 41 against the inclined surfaces of ribs 5 producing further rotation until teeth 41 locate in the next gaps between ribs 5. Contact arrangements are disclosed for single and double-pole on-off and changeover (Figs. 6 to 9, not shown).

Abstract: 798,652. Altering physical structure; working at specified temperatures; rolling. BOCHUMER VEREIN FUR GUSSSTAHLFABRIKATION AKT.-GES. Dec. 20, 1955 [Dec. 21, 1954], No. 36497/55. Class 83 (4). A process for refining and quality-improving by further treatment, steel which is hot rolled from billets or plate slabs and thereafter cooled without hardening, and, if required, already further worked in the cold to coil or bar form, is characterised in that, when subjected to further deformation by rolls or cylinders, the steel is heated by means of electric resistance heating in fractions of a second, preferably <SP>1</SP>/ 20 th of a second and less, to temperatures between 250‹ C. and slightly below AC3. The process enables a high rolling temperature to be chosen without prejudice to, e.g., a sorbitic structure obtaining from a previous heat treatment. Such structure can be still further improved by a heat treatment following the further deformation, such as air chilling or quenching or by tempering or annealing below AC3. The low voltage electric current, e.g. 10 volts, is supplied through the top roll to the bottom roll or vice versa, or by way of the rolls and an associated coiler or drawing pincers. The steel may be electrically heated and shaped either several times in immediate succession on a plurality of roll stands or by rolling to and fro uninterruptedly on one or two reversing stands. The electric current may be conducted by wheels connected to the rolls and immersed in a lead bath. Austenitic steels are electrically resistance heated to a temperature below that at which scaling begins.
